Laser therapy devices stimulate atoms to emit and amplify light at a certain wavelength. This light is used to manipulate certain reactions in your body. It can be used to relieve pain or even repair damaged tissue. You need to invest in a good laser therapy machine that will help you target body tissues and deliver the results you want.

However, seeing as there are different brands in the market it is important to understand what you need to consider.  The competition in prices makes it impossible to solely depend on price as a determinant. This is why you should look into other aspects of laser therapy equipment for consideration. Here are some of the things you should consider.

Wavelength is measured in nanometers (nm). The wavelength of a laser device determines the depth of penetration. The higher the wavelength the deeper the penetration.  The common wavelengths used in laser therapy range from 620 nm to 1000 nm. 


This is a shorter wavelength that penetrates a distance of up to 1 centimeter. This laser device is perfect for treating wounds, stimulating acupuncture points, and lymphatic tissues. When you use a laser therapy device with this wavelength, you can expect an increase in blood circulation and improved metabolism. This is mainly because the blood can easily absorb the energy from the laser light.


This wavelength comes with a penetration distance of up to 5 centimeters. It comes in handy when treating tendons, ligaments, and tissues. It interacts with the mitochondria to speed up the metabolism of tissues and repair damaged cells. 

900nm -1000nm

This is a class 4 laser that provides a lot of energy when used on your body. The energy is converted to heat which is absorbed by your body tissues. This helps repair any damages and aids in the healing of any wounds. 

Class Level


There are 5 different class levels including class 1,2,3A,3B, and 4. These low-level laser therapy devices vary because of their power and efficiency. Laser therapy devices between classes 1-3A use very low power and may have no significant effect on your treatment. Class 3B laser devices have a power of 500 mW and can be used for homes as directed by a medical professional. 

Class 4 devices have a power output of more than 500mW and can damage the eyes and tissue if not properly used. However, this high power allows for enough energy to be passed to the nerves, muscles, and ligaments within a short time.

Pulsing Option


Different laser devices come with different pulse frequencies. These frequencies differ because they have different effects on the body. Low pulse frequencies are best suited for minor injuries while sub-acute injuries benefit from high pulse frequencies. For chronic pain, the only frequency that is sufficient enough is the continuous mode. Seeing the different pulsing options, you should consider what you intend to do with your device.



Laser therapy protocols are the things you need to observe when using these devices. It is almost like a manual that will guide you through. Most laser therapy devices include these protocols with their product packages. This is why you need to do your research to find out which laser machine manufacturers offer this as an option. 



Your laser therapy device has a power output that determines the efficiency of the treatment. When the power is high, then the time taken for treatment is greatly reduced. However, if the power is low then it will take much longer to deliver the same results. Consider this when getting a laser therapy device. This will help you decide whether the amount of time spent in treatment affects the choice you’ll make.



This is by far the most thought about factor when choosing a laser therapy device. You’ll want to consider the devices that fall under your budget and how flexible you are in adjusting it. If the device that meets all your expectations is a bit too pricey, consider checking with other suppliers. Remember, there are numerous brands in the market with competitive pricing. You are bound to find one that will check all the boxes. 


Choosing a laser therapy device requires you to be well informed about what laser therapy is and what is needed in a quality device. Take your time to go through all the factors that will influence your buying decision to make sure you make a wise one. Consult different manufacturers and remember to read the ratings and reviews sent by other users. This will help you see if what the device promises is what it delivers.
